## Definition: Femtomho

The SI prefix "femto" represents a factor of
10^{-15}, or in exponential notation, 1E-15.

So 1 femtomho = 10^{-15} mhos.

The definition of a mho is as follows:

The SI derived unit of electric conductance is the siemens, which was previously referred to by the term mho. That term came from spelling ohm backwards and was written with an upside-down capital Greek letter Omega. The term siemens, as it is an SI unit, is used universally in science and primarily in electrical applications, while mho is still used primarily in electronic applications.
